These are some preliminary results for the "tournament bracket"-style questions in the 2021 State of CSS survey.
The data is originally stored as a series of 7 triplets (for the four first-round match-ups, two semi-finals match-ups, and the finals) containing the first participants, the second participants, and the winner of each match. For example:
const bracketResult = [
[7, 6, 6], // first round
[4, 0, 0], // first round
[5, 2, 2], // first round
[3, 1, 3], // first round
